TO WHOM I'I MAY CONCERN: 4

l Be it known that I, ADRIEN I-IOUGET, of Verviers, in the Kingdom of Belgium, have invented certain new and useful improvements in Gigs; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings.

Gigs heretofore most generally inuse may be classified, first, into single-cylinder gigs and double-cylinder gigs. The'former may be subdivided into single-acting gigs and double-acting gigs. In both, however, in order to properly teazle the cloth in opposite directions, it is necessary to reverse the motion of the cloth and at the same time reverse the motion of the cylinder and the position of the teazlc-slats on the cylinder. To obviate loss of time and expenditure of labor attending this reversing of the slats and of the run of the cloth, and to produce a more even or uniform teazli'ng, double-cylinder gigs were contrived; that is, gigs in which two cylinders are used, one of which revolve/s in one direction, and the other in the opposite direction, while the cloth runs continuously in one direction. The first double-cylinder gigs were really duplicated gigs, t'. c., two gigs were so combinedas that the cloth passed through one of them first; then it was collected in a trough, whence it was taken up by and worked in the other gig. It will be readily understood that this system involves much labor, requires much power to 'drive the machinery, and aii'ords no means to properly watch the operation, upon the cloth. Other mprovements have been devised with a view of remedying these evils. For example, in the Gessner gig, which is the best double-cylinder gig heretofore in use, the cloth passes under the two cylinders, and thus is caused to receive the broken teazles and iiocks of'wool'; and these particles are afterwards pressed intc'the body of the cloth, and often cause the tearing of the fabric, particularly if it be fine. Besides, it is difficult to observe the manner in which the teazling is performed by reason of the limited length of the cloth which can be brought under the eye of the workman. In other double gigs, the cloth passes under the two cylinders, and then returns above and over the same. It thus receives in like manner the teazles or broken' pieces therefrom, and also the docks of wool. On the other hand, the height at which the cloth and cylinders are placed renders the operation of handling and inspecting the cloth extremely inconvenient, and the examination itself cannot be satisfactorily made on account of the partial obscuration of theilight in which the cloth :s seen. It is to remedy these and other' disadvantages which generally attend the use of double gigs whose drums or teazling cylinders are in juxtaposition, that I have invented or devised the arrangement of a doublecylinder gig, as indicated in the accompanying drawing, which represents a side elevation of a mill to which my improvements are applied.

The mill consists of a frame, G, in which the stretching and conducting rollers, and the cylinders which carry the teazles, have their bearings. The cylinders E F are mounted in the frame so as to be in juxtaposition and at the same height from the bottom ofy the frame, their axes lying in the same horizontal plane. They may be operated so as to revolve in similar or opposite directions, by means of a strap or connecting belt, either straight or crossed. .In the upper part of the frame above the cylinders are the rollers a, b, dto., geared together as shown in the drawing, and forming a system by means of which the cloth is fed along or regularly conducted through the mill. Under this arrangement the cloth is placed in a trough or basin, A, which is separated from the moving parts ofthe machine, so as to allow the operator free access to the machine, and, at the 'same time, to thoroughly examine the work in progress at the delivery end, or side marked at, of the machine. In order to reach the first teazling drum E, the cloth is extended above the Workman, over the roller B, placed in that part of the frame which overhangs the basin A. Around this roller B, or a pulley o'r drum mounted on its shaft, a strap, m, is passed, whose tension over the roller is regulated by means of a thumb-screw,p. The object of this arrangement is to give the cloth the amount of resistance requisite-toV bring it into proper tension while passing over or against the teazling cylinder. Passing over the succeeding roller B the cloth is carried under thc roller a, the first of the series of geared rollers. It is thence conducted successively over the roller b and downward under the expanding roller H, placed just over the upper part of the cylinder E. The cloth, as soon as ity leaves the roiler H, meets the drum E, and remains in contact therewith until it reaches the roller I, which is movable by means of the segmental rack o, operated by a crank-wheel, through the intermediary of a pinion and endless screw, 'so as to give more or less contact ofthe cloth with the teazle cylinder E at pleasure. The cloth, after passing around the roller I, reascends until. it meets the geared roller d, which is connected with the rollers -a b by the gear-.wheel c. It then passes over this roller d, and, traversing the space which intervenes between the two partsof the gig, -extends over the leading or conducting roller f, which is connected with the rollers over the rst teazling cylinder E by means of the large gear-wheel e. The'nee. it'is carried downward under the expanding roller K, and comes in'contact with the upper part of the teazlin'g drumj F, continuing in-sueh contact u'ntil it meets the roller L, which is movable in a similar manner and for the same purpose as the roller I. The cloth passes under and around the movable roller L, and thence extends upwards to the geared roller C. It is conducted over-this roller and down under the roller D, after which it is carried upwards and passed successively over the guide and supporting rollers M N O and draught-roller P, which may be covered with cards or any other material which will cause the adhesion of the cloth sic as to produce the required draught. From this latter roller the cloth falls again into the basin or trough A, being entirely' under the eye of the workman, who can easily manipulate it, or judge cf the quality of the work performed. The great length of the course traversed by the clot-h allows a correspondingly'great increase in the length of the cloth to be operated on at one working. For cloth which requires the perfect preservation of the nap in the condition in which it is left by the second'cylinder F, such cloth is taken' out en the rst roller C above the cylinder, and from this roller it is conducted over the rollers M N, &c., directly to the basin A, without passing under the roller'D, thus keeping its `tcazled side exterior to the conducting and guiding rollers. In the drawing, the course traversed by the cloth when brought in contact but once witheach cylinder is indicated in black lines. But the arrangement of rollers, Etc., necessary in order to give it, the double contact with each cylinder, as is sometimes done in gig-mills, can bc easily effected in the manner shown in red lines in the same drawing. 'It will be seen, however, that under either arrangement the cloth 'is brought in contact only witlrthe tops, or, at the furthest, 4no lower downthan with the sides of the cylinders, and that the cloth is in no degree carried underneath such cylinders, thus obviating the disadvantages recitedin the first part of this specification.

1 The principal advantages of this arrangement are, freedom of the workmen from danger, the perfect conducting of the cloth, without liability to injury from bits of teazles, flocks, or dirt; the facility with which it maybe examined and adjusted; the ease with which the machine may be operated, either for supplying the drums'with teazles or for regulating the contact ofthe cloth with the teazles; and, lastly, the increased length of the cloth, allowed by the length of the course which the cloth traverses in its move through the mill.

i Having thus described my invention, and the manner in which the same is or may be carried into el'ect, what I claim, and desire to secure by Letters-Patent, 'is as follows: y

In machines for raising the nap on cloth by means of two teazling drums, I claim the arrangement substantially asherein shown of the teazling drums, conducting and stretching rollers, and suitable gear mechanism for imparting to the cloth its move to, against, and from the said tcazling drums, and also to and from the receiving basin, in the manner and for the purposes set forth. i

In testimony whereof I have signed my name to this specification before two subscribing witnesses.
